J'AY SAMUEL BURWELL, OF SHARON, PENNSYLVANIA SHOCK ABSORBER.

Application filed January 8, 1826. Serial No. 80,036.

The present invention relates to. a shock absorber and has for its prime object to improve upon the structure shown in my pending a plication bearing Serial No. 59,- 863, filed ctober 1st, 1925.

An important object of the invention is to provide a shock absorber wherein a bowed plate is applied to the convex side of a semielliptical spring adjacent one end thereof and to provide a cushioning means in con nection with one end of said plate so as to prevent the breaking of theU-bolt or spring clip used to en age this end of the plate with the semi-e1 iptical spring. 1

Another important object of the invention is to provide a shock absorber of the above nature which is capable of being easil and fiiliickly applied and adjusted in relat on to t e spring and one which possesses a simle structure that will prove strong and urable in use. 7

With the above and numerous other objects in view as will appear as the descrip- 'tion proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of arts as will be hereinafter more fully descri d and.

claimed.

In the drawing Figure 1 is an elevation of a semi-elliptical spring showing my shock absorber associated therewith.

Figure 2 is a top plan view thereof, and Fi theredzlirough substantially on the line 3-3 of Fi 1.

Regi' ring to the drawing in detail, it will be seen that 5 designates any well known type of semi-elliptical spring. The nu meral 6 designates a plate which is curved so that its intermediate portion engages the convex side of the spring 5. One end of the plate 6 is engaged with the U-bolt 7, whilethe other en of the late 6 has a 3 ring clip 8 enga d therewit and the sides t ereof straddle t e bolt may enga in t e intermediate notch portion 9 of a tremities engaged wi the concave side of the sprin the inner end being with a U-s aped clip 11 which stra frame. 1

The notched or reversely curved intermediate portion 9 of the plate is normally aced from the concave side of the spring.

t will therefore be seen that when the dles the re 3 is a section taken transversely ring so that the end wed 1m 10 having its exprovided spring rebounds both the plates 6 and 10 will tend to absorb the shock and considerable strain will be taken off of the clip 8 as would be the case where no plate 10 were used, and the clip 8 was engaged directly with the spring. 7

It is thought that the construction, utility, and advantages of the invention willnow be clearly apparent without a more detailed description vthereof. The present embodiment of the invention has been disclosed in detail since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description. Numerous changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as, hereinafter claimed.

Having thus described the invention, what I claim as i new and desire to secure by Letters Patent is:

1. A shock absorber of the class described including a bowed plate having its intermediate portion adapted to abut the convex side of a spring and its ends spaced therefrom, a U-shaped bolt at one end of the plate for engagement with the spring, a U-shaped clip 'at the other end of the plate for straddling the spping, a second bowed plate havin 1ts ends 1n abutment with the- .concaved si e of the spring and having its intermediate portion curved inwardly and s aced from the s ring, means engaging the -shaped cli wit the intermediate portion of the secon late.

2. A shock a orber-of the class described including a bowed plate having its intermediate portion ada ted to abut the convex side of a spring an its ends spaced there'- from, a U-shaped bolt at one end of the plate for engagement with the s ring, a U- shaped cli at the other end 0 the plate for stradd 'ngthe' spring, a second bowed plate hav' 1ts ends in abutment with the concaved si es of the spring and having its intermediate portion" curved inwardly and s aced from t e ring, means engaging the -shaped clip wit the intermediate portion of the second plate. one end of the second plate being provided with U-shaped clip adapted to straddlethe' spring. I

3. A sh k absorber of the class described including a bowed plate having its intermediate portion adapted to abut the convex eemme side of e-sprin and; its ends spaced. theremeans engaging one end of the second plate from, a, second owed plate havin" its ends with the spring, and means for en in abutment with the concave side of the the other end of the first plate with the w spring and its intermediate portion curved spring. t inwardly and spaced from the spring, means In testimony whereof I aflix my signature. engaging said intermediate portion of the second plate and one end of the first plate, JAY SAMUEL BURWELL.
